uMap: Can I deactivate the right-click menu / context menu?

Hi. I have created a few maps on umap.openstreetmap.fr in the past and this week I made a new one. I don’t know if this is a new feature but it’s possible to right-click on the map (away from any objects) and get a context menu with entries like open browser, browse data, open in OpenSteetMap, directions, create isochromes, and more. My map is to support an event where users are just going to be interested in the objects I’ve added and in panning and zooming, none of the features in the context menu will be relevant. Also, on a mobile device, this menu is frequently triggered by panning and particularly zooming. It then covers up a major portion of the screen and closing it is not straightforward. All in all, the context menu is a distraction that I dearly would like to get rid of, but I can’t find out how. Can you help?

Out of interest, I also wonder how I could customise that menu, but in this example I only want to deactivate it.

Thanks for your replies :-)
